' Claims. (CI. 12-17) sole member. g

In certain well-known types of shoes such, for I example, as slippers,the outsole comprises a sole member having a body portion of felt, orother relatively soft and compressible Ymateri'aLwhich is faced on oneside with a piece of upper leather. This facing piece is larger than thesole'member so as to provide a marginal portion that extends beyond theedge of the sole member, when these two parts are initially assembled,and, in the next step in the manufacture ofI'a "faced: sole member ofthe aforementioned type, this margithe edge of the sole member andsecured in place, as by adhesive, to the oppositeside of the'solemember.

The aforementioned step is commonly pernal portion of the facing pieceis folded around formed by hand although machines for carrying" out thisfolding operation have been proposed.

These prior machines, however, merely, turn the marginal portion of thefacing piece upwardly into a position substantially parallel to theedgeof the sole member and then fold it in over. the

opposite side thereof, without exerting any definite tension thereon soas to draw. the marginal portion of the facing tightly around the edgeof the'sole member. Accordingly, with the facing piece thus ratherloosely conformed to the edge of the sole member, when the sole. memberis applied to a shoe, the weight of the wearer may so compress thematerial of the body of the sole member as to produce unsightly bulges,or wring kles, in the facing on the edge of the sole member.

It is an object of this invention to provide a novel and improvedmachine for conforming the marginal portion of a sole facing to the edgeof a sole member in which the facinglis tensioned so as to draw ittightly aroundthe edge of the sole member. With this object in view; theherein illustrated machine is provided with tensioning means for seizingthe marginal portion of a sole facing and drawing it snugly around theedge of a sole member, together with means for pressing the tensionedmarginal portion against the op,- posite face of the sole member; thetensioning means and pressing means being arranged to operateprogressivelyaround the peripheral edge of. the sole member.

For supporting the sole.

member and its attached facing piece during the aforementionedtensioning and pressing operations, and in accordance with a feature ofthis invention, the herein illustrated machine is provided with a tablewhich, preferably, is yieldably mounted so as to accommodate sole members of different thicknesses as well as sole members of non-uniformthickness. This table is pro;

vided with an upstanding deflecting member for turning the marginalportion of the facing piece upwardly into a position to be engaged bythe tensioning and pressing means.

' The above and other objects and features of the invention will appearin the following detailed de scription of the embodiment illustrated inthe accompanying drawings, and will be pointed out in the claims.

While various types of tensioning and pressing instrumentalities whichare available, for example, in'prior cement lasting machines, may beutilized for drawing the marginal portion of the sole facing around theedge of the sole member and for pressing the tensioned marginal portionagainst the opposite side of the sole member, I have found that thetensioning and pressing instrumentalities of the lasting machinedisclosed in United States Patent No. 2,411,827, granted on November 26,1946, in the name of Joseph Fossa, are particularly well adapted forthis purpose. Accordingly, the invention is here shown, for purposes ofillustration only, as embodied in a lasting machine of that type. a I

In the drawings,

"Fig. 1 is a view in side elevation of a machine embodying the featuresof this invention;

- "Fig." 2 is a view in front elevation of a portion of the machineshown in Fig. 1;

r Fig. 3 is a plan view showing certain of the operating elements of themachine shown in Fig. l, and

' Fig. 4 is a view of the machine shown in Fig. l withparts in differentoperating positions.

Referring now to these drawings, the machine "therein illustratedcomprises the same operating instrumentalities as those of the lastingmachine of the aforementioned patent, namely, a reciprocating gripperhaving a rear jaw in and a front jaw l2, a shoebottom rest and lastingshield member [4, a presser feed foot iii, a feed-retaining finger l8and an edge guide roll 20. These instrumentalities are all mounted on,and operatedby mechanism contained within, a hollow head constructionhaving a lower portion 24 and a removable top portion 26. Also, themachine is provided with mechanism, operated by a treadle, not shown,for moving the shoe-bottom rest and lasting shield membenhereinafterreferred to as the rest member, toward and away from the operatingposition in which it is shown, which mechanism is further adapted tohold the front jaw l2 away from the rear jaw I0 to facilitate thepresentation of the work to the machine. Inasmuch as the constructionand operation of these instrumentalities, as well as the operatingmechanism. therefor, is'set forth in detail in the aforementionedpatent, it will not be repeated here, and reference may be made to thatpatent for a description thereof. V l l For supporting a sole member Sand its facing F, the illustrated machine is provided with a fiat tableI which is mounted so as tohold the sole member yieldingly up againstthe rest member I4, in the following manner. Fixed to the table I00, andextending downwardly therefrom, are four rods I02 which pass throughbores I04 in bosses I66, formed integrally with a pair of angularlyshaped brackets I I0 and I I2. These brackets are secured to the lowerportion 24 of the head 22 by means of screws II4, I I4 and are connectedtogether by means of a transverse web I08. Surrounding each rod I02 is acoil spring H6 and these springs urge the table I06 upwardly, toward therest member I4, to the extent permitted by stop nuts '8 carried by therods I02.

When initially secured to the sole member S. the marginal portion of thefacing F extends outwardly from the edge of the sole member in themanner shown in Figs. 2 and 3. For turning this marginal portionupwardly and into a position where it will be engaged by the gripperjaws I0 and I2, a deflecting member I20, having a curved upper end I22,is provided. Referring to'Figs; 1 and 2, this deflecting. member issecured for vertical adjustment on a bracket I24 by' means of a screwI26 and a .dowel pin I28, the member I26 being slotted at I311 for thispurpose. I32, by means of a screw I34, and this bar is adjustablysecured to the web I08 by means of screws I36 which pass through anelongated slot I31 therein. The table I00 is recessed at I38 and I46,see Fig. 3, so as to provide clearance spaces forthe deflecting memberI20 and edge guide roll 20, respectively.

The operation of the machine which has just been described is asfollows. The operator takes a sole member S and, after manually foldingthe outstanding margin .of its facing F upwardly against the edge of'thesole member, in a selecting location, places the sole member on thetable I 06 and slides it in under the rest member I4 so that the foldedup portion of the margin of the facing is beneath the curved p er endI22 of the deflector I20 and the sole against the edge guide roll 26.Next, the operator depresses the treadle to swing the rest member I4 toits operative position'as shown, in which the rest member contacts theupper surface of the sole member and extends beneath the margin of itsfacing, see Figs. 2 and 4. This movement of the rest member to itsoperative position releases the front jaw I2 and permits it to movetoward the rear jaw ID, as in the machine of the abovementioned patent,so that the gripper is now rendered operative to seize the margin of thefacing and draw it snugly around the edge of the sole member, where itis immediately pressed against the upper surface of the sole member bythe presser-feed-foot I6. It will be under stood that theupper surfaceof the sole member, and/or the margin of the facing, have beenpreviously coated with a suitable adhesive so 1 that the margin of thefacing is adhesively secured to the sole member.

The presser-feed-foot, while in pressing .engagement with the margin ofthe facing, also moves in a direction to feed the sole member, while thefeed-retaining finger I8 operates to apply additional pressure to themargin of the facing and also to hold the sole member against retrogrademovement, during those intervals when the presser-feed-fo'ot isbackfeeding and The bracket I24 is fastened to a bar 4 the gripper istensioning the margin of the facing. These tensioning, feeding andpressing instrumentalities operate in the same manner as in the machinedescribed in the aforementioned patent.

As the sole facing F is thus being tensioned and pressed against theupper surface of the sole member S, progressively along the peripheraledge of the sole member, the operator merely guides and turns the solemember so as to keep its edge against the edge-guide roll 20, thedeflecting member I20 with its curved upper end I22 initially turningthe facing from its flat outstanding position upwardly to guide it intoa location in which it will be engaged by the gripper jaws II] and I2.Just before the operation' has proceeded entirely around the peripheryof a sole member, and as that portion of the margin of the facing whichwas first tensioned and pressed against the .sole member is nearlyreached, the operator depresses the treadle, thus withdrawing the restmember and rendering the gripper jaws II] and I2 inoperative, andpermits the presser-feed-foot I6 and feed-retaining finger I8 tocontinue to operate and complete the pressing of the margin against the.sole member, this short remaining portion having been substantiallytensioned by the effect of the gripper previously operating on oppositesides thereof.

During the above-described tensioning and feeding operations, the solemember S is yieldingly held up against the rest member I4 by the four.springs II6, the stop nuts IIB being so adjusted as to permit thisaction with the particular thickness of sole member being handled. Thesesprings, which .are relatively light so as to merely support the weightof the table with a sole thereon, also yield to permit the table to movedownwardly whena thicker portion of the sole member, e. g., the heelpart which is built up by means of a wedge block W, is passing beneaththe rest member I4, or when a sole member of greater thickness ispresented to the machine.

While the invention has been herein illustrated as embodied in a machineof the type disclosed in the above mentioned patent, it will beunderstood, of course, that in its broader aspects it is not limited tothe use of tensioning and pressing instrumentalities of the exactmechanical construction shown in said patent. Instead it is contemplatedthat the objects of this invention may be attained by associating theyieldable supporting table with other types of tensioning means.
